Intrusive thoughts and compulsive behaviors in postpartum women: Psychometric properties of the parental thoughts and behaviors checklist.

Background and AimPostpartum-specific obsessions and compulsions are common in postpartum women, but validated measures to comprehensively assess such symptoms are few. Therefore, the aim of the present study was to investigate the psychometric properties of a self-report version of the Parental Thoughts and Behaviors Checklist (PTBC) that assesses postpartum-specific intrusive thoughts, associate

Biologisk mångfald i urbana miljöer : förutsättningar, fördelar och förvaltning

Den ökande urbaniseringen leder till att städer breder ut sig över om-givande landskap, med förlust av jordbruksmark och naturmiljöer som följd. Ambitionen att städer inte skall breda ut sig leder istället till att kvarvarande naturliga, obebyggda och övergivna miljöer inom städer får stryka på foten till förmån för förtätad bebyggelse och infrastruktur. Urbaniseringen går på så sätt ut över biolo

Inventering av risken för förgiftning av bin med växtskyddsmedel av typen neonikotinoider under svenska förhållanden : Slutrapport 2015

EU har sedan 2013 begränsat användningen av tre neonikotinoider i grödor som är attraktiva för bin. En stor del av den kunskap vi har idag om hur bin påverkas av neonikotinoider kommer från laboratoriestudier av framförallt honungsbin som har matats med växtskyddsmedel. I ett forskningsprojekt har forskare från Lunds universitet och SLU i samarbete med Jordbruksverket undersökt hur ett växtskyddsm

Influence of the migration of radioactive contaminants in soil, resident occupancy, and variability in contamination on isodose lines for typical Northern European houses

In the remedial phase following an accidental radioactive release, it is important that soil decontamination measures are carried out on the areas that contribute most to the radiation dose. In this study, the newly developed concept of isodose lines was applied to the area around typical Swedish dwellings to identify these areas. The influence of the most common building materials in Sweden, wood

Sveriges största forskningssatsning på biologisk mångfald och ekosystemtjänster i ett föränderligt klimat

TEMA: BIODIVERSITET I CENTRUMEtt av Sveriges 43 nationella strategiska forskningsområden BECC – Biodiversity and Ecosystem services in a Changing Climate – fokuserar på biologisk mångfald och ekosystemtjänster i en värld präglad av klimatförändring. Med ett tvärvetenskapligt angreppssätt arbetar vi med hur svensk markanvändning kan förenas med en långsiktigt hållbar utveckling i ett föränderligt k

The functional interaction of EGF and PDGF with bradykinin in the proliferation of human gingival fibroblasts.

Epidermal growth factor (EGF) and platelet-derived growth factor (PDGF)-BB are both involved in periodontal wound healing. Each of these growth factors exerts a positive proliferative effect on cells of the periodontium in vitro. However, in vivo the peptide bradykinin is one of a complex array of mediators present in addition to these growth factors. The purposes of this investigation were to: 1)

The agonist binding site on the bovine bradykinin B2 receptor is adjacent to a sulfhydryl and is differentiated from the antagonist binding site by chemical cross-linking

Chemical cross-linking was used to analyze the binding sites for the agonist bradykinin (BK) and the antagonists NPC17731 and HOE140 on the bovine B2 bradykinin receptor. [3H]BK and [3H]NPC17731 bound with high affinity to the same B2 receptor in bovine myometrial membranes as determined by the total number of specific binding sites and pharmacological specificity of the binding of these two radio

Bortom debatten om integrerat eller segregerat bevarande

Den pågående klimatförändringen påverkar den biologiska mångfalden direkt,men också indirekt via klimatanpassning av skogs- och jordbruk. Det strategiskaforskningsområdet BECC fokuserar på bägge dessa utmaningar, för att bidra tillen kunskapsbas som gör att man kan fatta bra beslut om hur våra landskap skallskötas.

Antagonists of bradykinin that stabilize a G-protein-uncoupled state of the B2 receptor act as inverse agonists in rat myometrial cells

Several B2 bradykinin (BK) receptor-specific antagonists including HOE140, NPC17731, and NPC567 exhibited negative intrinsic activity, which was observed as a decrease in basal phosphoinositide hydrolysis in primary cultures of rat myometrial cells, and this response was opposite to that elicited by the agonist BK. The order of potency of the antagonists in attenuating basal activity was essential

Focal Adhesion-associated Proteins p125FAK and Paxillin Are Substrates for Bradykinin-stimulated Tyrosine Phosphorylation in Swiss 3T3 Cells

In this study we examined the involvement of the focal adhesion-associated proteins p125FAK and paxillin as substrates for bradykinin (BK)-stimulated tyrosine phosphorylation in Swiss 3T3 cells and the potential role of protein kinase C and Ca2+ in these events. BK (1 UM) stimulated tyrosine phosphorylation of p125FAK and paxillin. In addition, BK also increased the phosphotyrosine content of the

B1 and B2 kinin receptors on cultured rabbit superior mesenteric artery smooth muscle cells : Receptor-specific stimulation of inositol phosphate formation and arachidonic acid release by des-Arg9-bradykinin and bradykinin

In this study we investigated receptor-specific cellular signals elicited by kinin agonists in cultured rabbit superior mesenteric artery smooth muscle cells. Kinins promoted an increase in inositol phosphate formation and arachidonic acid release in these cells. The responses elicited by des- Arg9-bradykinin (des-Arg9-BK), a B1 kinin agonist, were antagonized by des- Arg9[Leu8]-BK, a B1 kinin ant

Identification of p125, a component of a group of 120-kDa proteins that are phosphorylated on tyrosine residues in response to bradykinin and bombesin stimulation, in anti-ras-GTPase-activating protein immunoprecipitates of swiss 3T3 Cells

Bradykinin (BK) and bombesin (BN) stimulate an increase in the tyrosine phosphorylation of a 120-kDa group of proteins (pps120) in Swiss 3T3 cells (Leeb-Lundberg, L. M. F., and Song X.-H. (1991) J. Biol. Chem. 266, 7746-7749). Here, we show that a component of pps120, p125, was specifically immunoprecipitated with antibodies against the p21ras GTPase-activating protein (GAP). The major portion of

Bradykinin receptors and signal transduction pathways in human fibroblasts : Integral role for extracellular calcium

Bradykinin receptors have been identified in human gingival fibroblasts; the primary signal transduction pathways and their dependence on calcium have been characterized. Binding data revealed a calcium-independent binding of bradykinin to the cell membrane with a receptor density of 25,000 receptors per cell and a K d of 1.6 nM. The bradykinin receptor-mediated activation of phospholipase C (PLC

B2 kinin receptor-mediated internalization of bradykinin in DDT1 MF-2 smooth muscle cells is paralleled by sequestration of the occupied receptors

We have previously shown that exposure of DDT1 MF-2 smooth muscle cells to the agonist bradykinin (BK) resuits in a rapid B2 kinin receptor-mediated internalization of BK followed by degradation of the intracellular BK [Munoz, C. M., and Leeb-Lundberg, L. M. F. (1992) J. Biol. Chem. 267, 303-309]. Here, we show that BK internalization is paralleled by sequestration of the occupied B2 receptors. Se

Bradykinin inhibition of EGF- and PDGF-induced DNA synthesis in human fibroblasts

Bradykinin exhibits proliferative influences in several types of cells; however, in the present study, bradykinin did not promote DNA synthesis but actually inhibited the DNA synthesis induced by epidermal growth factor (EGF) and platelet-derived growth factor (PDGF) in human gingival fibroblasts (HGF). This dose-dependent inhibitory effect was a specific intracellular interaction in that increas

Bradykinin binding to B2 kinin receptors and stimulation of phosphoinositide turnover and arachidonic acid release in primary cultures of cells from late pregnant rat myometrium

Primary cultures of cells from late pregnant rat myometrium contain B2 kinin receptors through which bradykinin (BK) stimulates inositol phosphate (InsP) formation and arachidonic acid (20:4) release. Equilibrium binding at 4°C revealed that [34H]BK identified a maximal number of cell surface B2 kinin receptor binding sites on rat myometrial cells of 308 ± 78 fmol/106 cells with apparently a singl
